iNiPROVEMENT IN WHEELWRIGHTS MACHINES.

Specification forming part of Letters Patent No. 149,984, date-d April 21, 1874; application tiled i February 9, 1874.

CASE C.

To all whom t may concern Be it known that I, MOSES O. BUFFINGTON, of Burlington, county of Des Moines and State of Iowa, have invented certain new and useful Improvements in NVheelwrights Machines, ot' which the following is a speciication: f j

The present invention relates to improvements in machinery for linishing the tenons on the end ot' spokes next to the hub; and it consists partly in the arrangement of an adjustable table for holding the spolie, with a rotary cutter for dressing ot't' the tenon, and partly in the arrangement of guards 011 Said table Jfor securing the spoke in the necessary positions, all as hereinafter ully described.

To enable those skilled in the art to understand and use my invention, I will now proceed to describe the manner in which the same is or may be carried into effect, by reference to the accompanying drawing, in which- Figures l and 2 represent side and top views, respectively, of a machine embodying my improvements. Fig. 3 is a vertical section of Fig. 2 on the line a' w, and Fig. 4 is a perspective view ot' the table i'or holding the spoke t0 be operated on.

The letters Ain the dra\.\'ing represent a portion oi' any ordinary wheelwrights machine, carrying a shalt, u, with a rotary cutter, a', upon one end. B B are standards secured by keys b I.) in the side of the frame A. C O are adj listing-screws, which pass upward through the outer ends oi" the standards B, and carry on their upper ends a slide, D. E is a table, notched at one end onto the slide I), so that it may have a movement transversely with the axis of the cutter af, and also be raised and lowered at its outer end slightly. G is a table with a transverse arm, g, supported above it upon screws gf g', by which its height may be adjusted. H is a block, secured tothe upper side of the table G. I is also a block, attached to the table G by pins it, and made adjustable in height by a setscrew, c", and provided on one side with a gage-screw pin, i. J is also a block, made adjustable vertically 011 the table G by a setscrew, j, and has a step upon one side, in the vertical side of which a gage-screw pin a is seated. L is a clamp-lever, pivoted at one end in a standard, l, projected upward from the table G. m is a common wheel-spoke.

The operation of my invention is as follows: The table E, being seated on its supports D and g, may be adjusted at the desired angle horizontally by the screws O and g g', so that, when the spoke m is placed thereon, with one shoulder ofthe square tenon. on its larger end resting against the block H, as shown by full lines at all of the figures, and the cam L brought down upon it, the table E maybe pushed to the right hand, and the end ot' the spokes passing beneath the rotating cutter a be dressed to any desired, and to a uniform, thickness of tenon. The spoke may then be placed as shown by dot-ted lines at Fig. 4, the height of t-he block I having been tirst adjusted to regulate the sides of the tenon, the

screw z" being adjusted to regulate its length upon the spoke by means of the lower shoulder resting against its end, and the screw nv being adjusted to regulate the transverse line of the shoulders, when, by again pushing the table E to the right, the sides ot' the tenons may be cut rapidly, smoothly, and, what is so desirable, with great uniformity of size.

I claiml. The table E, when adjustably and mov@ ably seated upon the bars D and g, and arranged to operate with the block H and cutter a, substantially as described, and for the purpose specied.

2. The blocks I and J, when adjustably se cured upon the table, E, as set fort-h, and arranged to operate with the bars D and g, ad j ustably attac-hed to their respective supports, as described, and with the cutter c', substantially as described, and for the purpose specitied.
